The present disclosure describes a directional radio frequency identification (RFID) system, which provides directional RFID tag scanning using RFID enclosures and moveable radio signal blocking components. The RFID systems herein also prevent unwanted RFID tag activation and focuses RFID readers on specific scan areas. The directional RFID systems may be implemented in any type of system that utilizes RFID tag reading, such as a point of sale systems and other related systems, which utilize RFID scanning.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
4. The method of claim 1, wherein the RFID reader comprises a plurality of RFID antennas, wherein a first subset of the plurality of RFID antennas is positioned within the RFID enclosure to scan the first scan area, and wherein a second subset of the plurality of RFID antennas is positioned the RFID enclosure to scan the second scan area.
This invention relates to an RFID (Radio Frequency Identification) system designed to enhance tracking and scanning efficiency in environments requiring multiple scan zones. The system addresses the challenge of accurately detecting and managing RFID-tagged items across distinct areas without physical obstructions or interference. The RFID reader includes multiple antennas strategically positioned within an enclosure to create separate scan zones. A first group of antennas is arranged to scan a primary area, while a second group is configured to scan a secondary area. This configuration allows simultaneous or sequential scanning of different regions, improving coverage and reducing the need for manual intervention. The system ensures that items tagged with RFID transponders are detected reliably in both zones, even when they are in close proximity or moving between areas. The enclosure housing the antennas may be designed to minimize signal interference and optimize read range, ensuring accurate data collection. The system can be integrated into various applications, such as inventory management, logistics, or security, where precise tracking of tagged items is essential. By using multiple antennas, the system enhances detection accuracy and reduces the likelihood of missed reads, improving overall operational efficiency.
10. The RFID system of claim 7, wherein the RFID reader comprises a moveable RFID antenna, wherein the moveable RFID antenna is in a first position directed at the first opening when the at least one moveable radio signal blocking component is in the first configuration, wherein the moveable RFID antenna is in a second position directed at the second opening when the moveable radio signal blocking component is in the second configuration.
This invention relates to an RFID (Radio-Frequency Identification) system designed to selectively read RFID tags in a controlled environment, such as a secure access point or inventory management system. The system addresses the problem of unintentionally reading RFID tags outside a designated area, which can lead to security breaches or inaccurate inventory tracking. The RFID system includes an RFID reader with a moveable antenna and at least one moveable radio signal blocking component. The blocking component can switch between at least two configurations to selectively block or allow radio signals. In a first configuration, the blocking component restricts signal transmission to a first opening, directing the RFID reader's antenna toward that opening. In a second configuration, the blocking component shifts to allow signal transmission to a second opening, repositioning the antenna accordingly. This dynamic adjustment ensures that the RFID reader only interacts with tags in the intended area, preventing interference from external or unauthorized tags. The system enhances security and accuracy by physically controlling the direction of RFID signal transmission based on the configuration of the blocking component.
11. The RFID system of claim 7, wherein the RFID reader comprises a plurality of RFID antennas, wherein a first subset of the plurality of RFID antennas is positioned to scan the first opening, and wherein a second subset of the plurality of RFID antennas is positioned to scan the second opening.
This invention relates to an RFID (Radio Frequency Identification) system designed for monitoring and tracking items passing through multiple openings, such as doors or gates. The system addresses the challenge of accurately detecting and identifying RFID-tagged items in environments where multiple entry or exit points exist, ensuring reliable tracking and preventing errors due to overlapping or missed scans. The RFID system includes an RFID reader equipped with multiple antennas. A first group of these antennas is specifically positioned to scan a first opening, while a second group is positioned to scan a second opening. This arrangement allows simultaneous or independent monitoring of both openings, improving efficiency and accuracy in tracking items as they move through different points. The system may also include additional components, such as a controller or processor, to manage data collection, analyze RFID signals, and ensure proper identification of tagged items. By using separate antenna subsets for each opening, the system minimizes interference and ensures that items passing through one opening do not affect scans at the other. This design is particularly useful in applications like inventory management, security checkpoints, or automated sorting systems where precise tracking of items is critical. The system enhances reliability and reduces the risk of misidentification or missed detections, making it suitable for high-traffic or high-security environments.
15. The POS system of claim 12, wherein the RFID reader comprises a plurality of RFID antennas, wherein a first subset of the plurality of RFID antennas is positioned to scan the first scan area, and wherein a second subset of the plurality of RFID antennas is positioned to scan the second scan area.
A point-of-sale (POS) system is designed to improve inventory tracking and transaction processing by integrating radio-frequency identification (RFID) technology. The system addresses inefficiencies in traditional POS systems, such as manual item scanning and inaccurate inventory management, by automating the detection and identification of items using RFID tags. The POS system includes an RFID reader with multiple antennas to scan different areas. A first group of antennas is positioned to scan a first designated area, such as a checkout zone, while a second group of antennas scans a second area, such as a storage or display section. This configuration allows simultaneous monitoring of multiple zones, enhancing operational efficiency by reducing the need for manual intervention. The system may also include additional components like a display, a payment processor, and a database to manage transaction data and inventory records. The use of multiple antennas ensures comprehensive coverage, minimizing missed scans and improving accuracy in item detection. This setup is particularly useful in retail environments where real-time inventory tracking and seamless checkout processes are critical. The system may further integrate with other POS functionalities, such as barcode scanning and customer interaction interfaces, to provide a unified solution for modern retail operations.
